Fig. 3 is a spacingdogs 18. Any other suitable means may beprovided for supporting, guiding, and releasing the spacing-rack, or thedogs may be mounted on the carriage and the rack upon the frame of themachine in a well-known manner.

The guide-rail may be secured at each end in forwardly-extending arms ofstandards 22 23, which are fastened to the top plate and connected by along horizontal bar 24 in rear of the guide-rail, and about midway ofthe bar 24 a third forwardly-extending arm 26 may be arranged so as tofurnish additional support for the guide-rail. The guide-rail may besupported in any other suitable manner, and so long as it is laterallymotionless it is immaterial to my invention whether it moves endwise orrotates in its bearings or not.

The platen-shifter may be hinged directly upon the guide-rail and mayconsist of two end disks or working portions 30 31 (which are eccentricto the guide-rail) and an intermediate cut-away portion 32, Fig. 3. As apreferred means for turning the'shifter about the shaft-axis a series oflongitudinally-extending teeth 33 are out upon the under side of thebody or cut-away portion 32 thereof,

Figs. 1 and 2, and a pinion 34 is arranged in mesh therewith, the pinionbeing operated by a finger-key 35 through a lever 36, which is pivotedbetween its ends at 37 to the side wall of the machine-base andconnected at its rear end by means of a vertically-arranged thrust-rod40 to the free end of a crank-arm 41, which is secured upon a horizontalshaft 42, extending parallel with the guide-rail 20, to a point aboutmidway of the machine where the pinion 34 is secured thereon, andsuitably mounted in brackets 38 39, secured to the top plate.

A suitable rectangular platen-frame 46 47 48, in which is supported theusual cylindrical platen 53, may be provided with rearwardly-extendinghinge arms or ears 50 51, perforated so as to engage the eccentric disks3O 31, so that the platen-frame is partly supported upon the shifter andso that when the shifter turns upon the rail-axis the platenframe iscaused to move transversely to the line of writing.

For returning the parts to normal position a spiral spring may bearranged upon the shaft 42, one end being fastened to the top plate andthe other end secured to the shaft by means of a tension-adjustingcollar 56.

If desired, adjustable stops 61 may be arranged upon the bracket 38 forlimiting the movement in either direction of the pinion, andconsequently of the shifter and the platen.

The platen-shifter and the ears 5O 51 of the platen-frame are preferablyconfined between the arms 16 17 of the rack-bar frame,to which thecarriage-propelling power is preferably applied, a cord 62 being securedat one end to an ear 63, projecting rearwardly from the rack, and at theother end to the usual springdrum 64, Fig. 4.

The platen-frame when swung up may be partly supported by a roll 65,which is mount ed upon the free end of an arm 66, projecting upwardlyfrom about midway of the rear bar 45 of the platen-frame and which runsupon the bar or rail 24.

In operation when the finger-key 35 is depressed the rear end ofkey-lever 36 rises and by means of link 40 swings up arm 41, therebyrocking shaft 42 and the pinion 34 thereon, so that the platen-shifterin mesh with the pinion is caused to turn upon the rail 20 and by meansof its eccentric construction draws the platen-frame and platenrearwardly. The positions of the parts when the shift-key is depressedare shown in full lines at Fig. 2. The normal positions of the shiftkey,eccentric, and platen are indicated by dotted lines. The long teeth 33upon the shifter enable the platen to be shifted at all positions in itstravel. Any wear to which the gear-teeth may be subjected, due to thesliding action thereof, will not perceptibly affect the rigidity of theplaten,since the transverse movement of the platen-frame is much lessthan the peripheral movement of the teeth 33.

It will be observed that the platen-frame when swung up turns upon theeccentrics and remains positively connected to the shifter, suchmovement of the platen-frame tending to hold the shifter more firmly innormal position, thus avoiding the erratic movements of the platen-frameheretofore experienced by reason of the disconnection of the platenframefrom the shift-rail. The stops for limiting the transverse movements ofthe platen are preferably arranged upon the framework of the machineinstead of upon the shifter or carriage, thus obviating friction betweenthe pinion and the shifter as the latter slides along, such as wouldoccur if a stop were to be placed upon the carriage to limit themovement of the shifter, and hence of the fingerkey 36, inasmuch as insuch a case the pressure of the finger of the operator would becommunicated to the stop through the pinion and the shifter during thelengthwise movements of the latter. To the same end the returning-springis also arranged upon a nontraveling portion of the machine.

So long as the key-actuated platen-shifter rides along alaterally-motionless guide-rail it is immaterial to my invention,considered in .its broad features, whether or not the shifter issupported directly upon the rail or upon some portion of the travelingmechanism or works upon the eccentric principle or is provided withgear-teeth or has a hinge action, as it may vary widely in constructionand arrangement without deviating from the invention, considered in itsbroader features.

Ball-bearing h'mge.ln the modification illustrated at Fig. 6 aball-bearing hinge is provided. between the shifter and the platenframe.The eccentric disks are provided with outturned cone-faces 70, and thehinge-arms are cupped at 71, the balls 72 being disposed between cup andcone in a manner common in bicycle construction. If desired, one of thearms 51 may be made adjustable lengthwise of the rear bar of theplaten-frame, so as to secure a nice fit of the hinge and take upsubsequent wear, and to this end the arm 51 is provided with one or twoslotted ears 73, secured to bar 4:5 by screws 74, the slots permittingthe required adjustment. Other suitable ball-bearing construction andadjustment may be employed.

Traveling bcZZ-bcctring.As illustrated at Figs. 9 and 11, theplaten-shifter. may be of tubular construction, and balls may bearranged about the guiderail and confined within the tube, so as totravel endwise along the guide-rail and also around the rail, thussecuring easy longitudinal and turning movements of the shifter, whichis designated as 83 and fits closely over the balls. To hold the ballsin position, a cage 81 may be employed, preferably tubular and providedat each end with one or more circular series of perforations 82, withineach of which is confined a ball, and also with an internal ring 85 forsupporting it upon the guiderail. The eccentric disks may be providedwith inwardly'projecting rims 8% to slip upon and secure to the ends oftube 83, and the perforations in the disks should be larger than theguide-rail.

Carriage-releasa-At Figs. 9 and 11 the rack-frame isillustrated asprovided with the usual forwardly-projecting finger-piece 8e. Anupwardly-extending integrai finger-piece 85 is also provided to be usedwhen the platenframe is swung up, being so arranged as to be readilydrawn forward by the hand that lifts the platen-frame, thereby releasingthe rack from the spacing-dogs.

Roller-track, Figs. 2, 6, and 7 .The broad ened front roll of theplatenframe rides upon a long antifriction-roller track 91, extendingparallel with the platen and provided with any suitable stationarysuppo'rt,such as a bar 92, secured upon posts 93, rising from the topplate. The roller 91 rolls to and fro as the platen shifts, and to keepit at all times parallel with the platen each end thereof may beprovided with gear-teeth 94, meshing with stationary racks 95, securedat each end of bar 92, the rack being provided with a guard portion 96to prevent displacement of the roller. The roller may be capped at eachend, as at 97, to prevent end wise displacement.

A modified construction for keeping the roller parallel is illustratedat Fig. 8, a rockshaft 100 being journaled in the standards 93 andprovided at its ends with upwardly-extending slotted arms 101, whichengage pivoi s or nipples 102, formed upon the ends of the roller. It isnot essential, however, that any means be provided for keeping theroller 91 parallel with the platen.

So far as my platen-shifter is concerned any other suitable support maybe provided for the opposite portion of the platen-frame,

and the roller-track is likewise adapted for use in connection withother shifting means.

Other portions of my invention may be used separately-as, for instance,illustrated in the construction at Fig. 10, in which the ball-bearingtube 83 is rigidly secured to a non-shifting platen-frame, securing arigid, easy-running, and durable construction, besides permitting theplaten-frame to swing up for inspection of the writing.

Numerous other variations in detail construct-ion may be made within thescope of the invention, and although certain claims herein coverpreferred specific constructions I do not wish to be considered as beinglimited thereto as far as the broader features of my invention areconcerned.

By the term shifter, wherever used in the specification or claims, Imean a device which forms a portion of acarriage and is arranged betweena platen-frame and a latererally-motionless guide-rail and which isadapted to cause transverse movements of said-platen-frame relatively tosaid guiderail and which, further, is connected to a key Whose positionrelatively to the keyboard does not vary at the letter-spacing movementsof the machine. Preferably the platenframe is guided upon the rail bymeans of the shifter. In carrying out this feature of my invention Iprefer to hinge the shifter directly upon the guide-rail, so that theguiderail is the axis of the hinge; but it is not essential in adaptingthe invention to other machines that the guide-rail be arrangedconcentrically with the shifter-hinge, as the shifter may haveanysnitable hinge, so long as it is enabled to turn upon said hinge tocause a transverse movement of the platen and so long as the shifter isprovided with suitable means for enabling it to ride or travel endwisealong the laterally-motionless guide-rail. It is not essential that theshifter be given a transverse movement by means of a hinge construction.Many portions of my invention are suitable for machines in which thepaper remains stationary while the types are arranged upon astep-by-step-moving frame, and I consider such a type-carrying frame asthe equivalent of the platen-frame referred to herein.

It will be observed that I have connected a finger-key to means whichare pivoted upon the frame of the machine and directly engage aplaten-frame shifter, so as to operate the same at all points in thelongitudinal or step-by-step travel thereof, said shifter being adaptedto travel along a laterally-motionless guide-rail and said platen-framebeing preferably hinged to the shifter, whereby it is enabled to shifttransversely and also to swing up to exhibit the writing, whether in itsnormal or shifted position, that the bar 24 and roller 65 limit theupward movement of the platen-frame, and that a letter-spacing rack orrack-frame is constructed to ride along said rail, together with saidshifter and said platen- ICC IIO

frame. It will further be noted that the shifter preferably comprises aneccentric or a pair of eccentrics, the periphery whereof serves as theplaten-frame hinge, upon which the latter is both shifted and turned up,the eccentrics being key-operated and rigidly united and hinged directlyupon the guiderail, and that the platen-frame is provided with eyes orrings 50 51, which operate as straps upon the eccentrics and whichsurround the guide-rail, so that the platen-frame swings about theguide-rail. It will also be seen that I provide a spring-drivenletterspacing rack or rack-frame which engages or is carried upon theguide'rail and is also preferably provided with an independent support,as 21, and which is adapted to move or carry the shifter andplaten-frame in letter-space direction, and that preferably theeccentric which operates the platen-frame is confined between the armsof the rack or rack-frame. It will also be seen that as an independentfront support for the platenframe I have provided an antifrictioncylindrical track, which is adapted to tumor roll crosswise of itslength during the transverse movements ofthe platen-frame, thatpreferably said track rolls upon or over a plane surface or surfaces,and that the turning or rolling motion of the track is caused by thepressure or weight of the platen-frame thereon.
